Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 1,101,445, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 1,101,445 | |
| -1 | -1,101,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,101,445.
Example:
1 x 1,101,445 = 1,101,445
and
-1 x -1,101,445 = 1,101,445
Notice both answers equal 1,101,445
With that explanation out of the way, let's continue. Next, we take the number 1,101,445 and divide it by 2:
1,101,445 ÷ 2 = 550,722.5
If the quotient is a whole number, then 2 and 550,722.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 1,101,445 | |
| -1 | -1,101,445 |
Now, we try dividing 1,101,445 by 3:
1,101,445 ÷ 3 = 367,148.3333
If the quotient is a whole number, then 3 and 367,148.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 1,101,445 | |
| -1 | -1,101,445 |
Let's try dividing by 4:
1,101,445 ÷ 4 = 275,361.25
If the quotient is a whole number, then 4 and 275,361.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 1,101,445 | |
| -1 | 1,101,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 47 | 109 | 215 | 235 | 545 | 2,021 | 4,687 | 5,123 | 10,105 | 23,435 | 25,615 | 220,289 | 1,101,445 |
| -1 | -5 | -43 | -47 | -109 | -215 | -235 | -545 | -2,021 | -4,687 | -5,123 | -10,105 | -23,435 | -25,615 | -220,289 | -1,101,445 |
